To all whom/t may concern Be it known that I, ANTHONY V. KEY- ROUSE, a citizen of the United States, and a resident of New York, in the county and State of the same name, have invented certain new and useful Improvements in' Window-Ventilators, of which the following is a specification.

T his invention relates to improvements inv ventilators and particularly to that class adapted to be used in connection with ordinary Windows and apertures in the walls of buildings designed for the intake or outlet of air or the circulation of air.

The objects arehfirst, to provide a ventilator that can be applied or removed and which is reversible so that an incoming air current 1s dlverted elther up or ldown as the accompanying drawings, forming part` of this specification, and in which:

Figure 1- is a partial side elevation of the ventilator, parts being broken away showing the construction. Fig. 2 is a transverse section of the same taken on line 2-2 of Fig. 1. Fig. 3 is a partial lrear elevation of the same. Fig. 4 is a front view of the upper slide. Fig. 5 is a cross section of the samev taken on line 5-5 ofFig. 4. Fig. 6 is a similar view ofthe lower slide. Fig. 7 is a cross section of the same taken on line 7-7 of Fig. 6. Fig. 8 is a perspective view of a window showing one of the applications of the invention, and,- Fig. 9 is a partial perspective view of the ventilator.

metal adapted to extend acrossa window frame, the lower part of the sash of whichv is normally received in the openbox-like tends rearwardl and outward from the main portion, the upper part 11 of which presents an obliquely disposed curved face, the loweredge being turned rentra'ntly for a short distance, as at 12, andA then turned down and to the front, forming a concave surface 13 through which are a number of openings The invention comprises a plate of sheet.

14, ranging from the upper portion of the concave surface to practicallyy the lowermost point 15 after which the metal is curved up and doubled as at 16 and again downwardly, curving in as at 17, to another angular position 18,*ithen downwardly and lnwardly forming a second 'concave surface 19, provided with openings 20 and a double member 21, the metal then extending in a curve downwardly and rearwardly as at 22, being finally doubled again at 23 and formed at the bottom 24 inthe same manner as the upper part 10, the whole presenting a sinuous profile. The end edges 25 are folded in the same manner as the side edges 10 and 24 so asV to presenta continuous groove around the entire structure so that the ventilator can be applied 1n any posi? tion. l The doubled metal at 23 and 11 is arranged to confine a sheet of wire netting 30, the same extending entirely over the rear portion of the ventilator so that insects and wind carried objects are excluded.

The front surface 17 is provided with an.

opening 31 through which extends a knob to ay projection 33 of the slide or shutter 34. This slide is provided with an angular upper edge 35 adapted to engage with the 32, the same being attached at its inner .end

folded edge 12, while the lower edge 36'is Y adapted to slidably engage. within an angle formed at 16. This slide or shutter 34 is provided with a plurality of openings 37 which coperate with the openings 14 in the main structure. so as to furnish a fully openedaperture or close the same when. op-

erated with the knob 32. 'The lower openings 20 are similarly provided with a sliding shutter 40 havingopenings41 and an engaging upper edge 42, which co-acts with the angular edge 18 and also with the internalv angle formed at v21, by the lower edge 43; the slide 40 being provided with a knob 45-slidable within the slot 46, formed in the front plate 19. Thus it will be seen that means are provided for closing the openings.

14 and 20, either fully or to such an extent as may be desired by merely operating the knobs 32 and 45, and it will be seen that the entering air current is arrested or diverted angularly upward. Y

Rearward of the portion 22 is a trough-like receptacle 50. having an upper member 51 secured to the front plate of the structure and adapted to contain a liquid as vshown at.v

aoL

a--a, so that air, in its passage through the several openings may take up such vapors or aromas as may arise from the liquid therein, which may be water, or any suitable antiseptic or liquid perfume desired. Use also may be made of the roll 55, which is revolubly mounted between the end plates 56, the same conforming to the shape of the front member and to which it is secured; this roll is preferably located midway of the ventilator, between the rows .of openings longitudinally thereof, rearward of the plate 17, and covered with a suitable fabric, the same being provided with antiseptics or perfumes in powdered form so that the air in passing will take up some of the atoms direct. A v

In application, the window sash is raised to admit of entering the ventilator below, and which as indicated may be applied either side up so that the air may be diverted up or down; in narrow windows of certain kinds, the apparatus may be applied 1 vertically, eXtra spaces being filled in any convenient manner. Thus I have provided an apparatuswhich allows a controlled air circulation, dlvertlng the same so as to avoid `direct drafts and having combined means for cooling, purifying and perfuming the lncomlng current, as well as means for preventing the entrance of noxious and undesirable insects, leaves and the like borne in the air.

Having thus described my invention, what `I claim as new and desire to lsecure by Letters Patent, is

1. In a window ventilator, a sinuously formed integral front plate folded upon itself intermediate of its edges, the portion of double thickness thus formed being inclined inwardly, there being openings in said plate behind said inwardly inclined portion thereof, and shutters for controlling the openings.

2. A window ventilator comprising an apertured plate having grooves at both upper and lower edges thereof adapted to receive and embrace the lower edge of a sash, whereby the ventilator may be used in either an inverted or an upright position.

3. A window ventilator comprising an ap- .ertured plate having inclined portions for deflecting the air currents out of a horizontal path, said plate also having grooves at both upper and lower edges thereof adapted to receive and embrace the lower edge of a sash, whereby the ventilator may be used in either an inverted or an upright position for delecting the air currents either downward or upward, respectively.

4. A window ventilator comprising an apertured plate having a continuous groove extending all around its four edges adapted to receive and embrace the lower edge of a sash, whereby the ventilator Amay be used with either side or end up.

In testimony whereof I have signed my name, to this specification in the presence of two subscribing witnesses.
